Resumen
El principal componente del sistema inmunitario de los vertebrados está mediado por los leucocitos. En aves existen cinco tipos: heterófilos, eosinófilos, basófilos, linfocitos y monocitos. El objetivo de este trabajo es presentar los conteos leucocitarios obtenidos a partir del análisis de frotis sanguíneos para un ave migratoria de larga distancia, el Playero Rojizo (Calidris canutus rufa) en el sitio de invernada Río Grande, Tierra del Fuego, y durante la escala trófica en Bahía San Antonio, Río Negro, Argentina. Como se observa en general para las aves, los heterófilos y los linfocitos predominaron en ambos sitios, mientras que el resto de los leucocitos se observaron en menor proporción.
